4 types of mineral fertilizer spreaders

Fertilization is an important point in agricultural activities. Since the harvest will directly depend on the saturation of the soil with micronutrients. To manage to handle large areas on time and not to disrupt the time of planting crops created special devices called mineral fertilizer spreaders.

Why fertilizer spreaders

Mineral spreaders - a highly specialized apparatusfor fertilizing the land and in the presence of the distribution function of seeds. This is a great opportunity to cultivate large areas in a short time, thereby increasing the efficiency of any agricultural land.

Types of machines for the distribution of fertilizer

Agricultural units for the distribution of mineral fertilizers may be additionally equipped with the functions of mixing, grinding and transportation.

Actually spreaders are divided into mounted, trailed, disc mounted and pendulum mounted. About them further the speech will go.

Mineral fertilizer spreader


The mounted spreader can, with its power, be “tied up” with a tractor. It is carried out in the form of a frame and a special hinged device, securely fastened on top of the bunker. There are also a couple of unloading grids, which prevent large elements from getting inside the unit. In the lower part of the device there are special funnels for spreading fertilizers.

The distinguishing feature of any attachment is the presence of distribution discs.

In the process of their failure, they can be replaced. During the operation of the unit, the fertilizers through the shaft fall from the bunker to the distribution discs, which rotate in opposite directions. And fertilizers are evenly distributed on the treated surface.

Mounted spreader


Trailed aggregates are distinguished by high productivity of the distribution of nutrients and sowing of seeds, even at minimal pressure.

This unit consists of a body, conveyor, dispenser and drive mechanism. To control the seeding, it is necessary to change the speed of movement of the conveyor and the width of the slit, which occurs under the action of the flap.

Trailed units are considered the most common. They look like a trailer, from which they got their name. But the accuracy of the distribution of mineral fertilizers in this case wants the best.

Mounted discs

Mounted disc spreaders must have special discs and blades made of stainless steel, as well as a propeller shaft. In order to regulate the amount of fertilizer spreading from the cab of the driver by hydraulic transmission, special dampers are present.

Due to the change of their position, the concentration of the distribution of mineral components over the land plot is monitored. In order to prevent clumping and ingress of large particles inside the device, the unit was equipped with agitators and safety nets.

Disc spreader

Pendulum mounted

The production of pendulum mounted spreaders occurs exclusively abroad. Therefore, the popularity of such units for our country is much lower. In this case, the main working body is not a disk, but a special swing tube.

To ensure the strength and performance of this part it is made of high-quality plastic. The tube moves through reciprocating action through the shaft. But It is worth noting that the pendulum mounted mineral fertilizer spreaders are somewhat inferior in disc productivity in their performance.

Plus, they are very noisy and unevenly distribute nutrients over the land plot.

Pendulum spreader

Pros and cons of spreaders

Any agricultural equipment is designed to simplify agricultural work. And the mineral spreader is no exception. It has its advantages and disadvantages, which will be discussed further.

Positive qualities of the unit:

  • speed of movement of feeding substances to the destination;
  • the possibility of feeding the nutrient compositions of large areas;
  • the speed and uniformity of distribution of fertilizers in the treated area;
  • , regardless of the type of unit, fertilizers are applied to the soil exclusively in the process of transport;
  • distinguish between spreader models that have the function of controlling the amount of fertilizer distributed. In other words, you can increase the concentration of nutrients where necessary, and reduce where the soil is already fertile. For entrepreneurs of the agrarian sector, this is a big saving of their financial resources.

In addition, such units can be used not only for their intended purpose, but also to disperse the seeds.

Negative qualities of the unit:

  • high cost of the device. If the farm is small, then the small entrepreneur does not have the opportunity to buy such equipment. And then the decision is made to do everything manually.
Automatic spreading of fertilizers saves time spent on manual labor.

How to do it yourself

But for this you need to understand his device. You need a box with eleven holes, which will be further protected by rotating plates. Moreover, above the surface of each plate there are two diverters. To control the supply of raw materials you need to have a damper. Two travel wheels serve as support.

The functionality of the device will be provided by transmitting torque from the wheels to the plates, well, and then to the shaft itself. Fertilizer plates are dropped from the box directly to the ground. In order to ensure uniform fertilizer intake, it is necessary to agitate the plates at regular intervals.

Mineral spreader is a great helper for any farmer. But not everyone can afford such a technique. In this case, you can make a simplified homemade version. After all, it is better to let it make a specialized unit, and not a person.
